DAVIS, OF CAIRO, GEORGIA, ASSIGNOR TO ill. G. DAVIS, OF SAME PLACE.-

FERTILIZER-DISTRIBUTER.

ESPBCIFICATION forming part of Letters Patent No. 441,791, dated December 2, 1890.

Application filed July 12, 1890- Serial No. 358,568. (No model.)

To all whom it may concern:

Be it known that I, WILSON A. DAVIS, a citizen of the United States, residing at Cairo, in the county of Thomas and State of Georgia,

have invented a new and useful Fertilizer- Distributer, of which the following is a specification.

This invention has relation to fertilizer-distributers; and the objects in view are to pro- Io vide a machine for the above purpose, the

same being adapted to open a furrow, distribute the fertilizer, and cover said furrow.

A further object of the invention is to provide means for thoroughly pulverizing the fertilizer previous to its distribution, and to provide means for regulating the quantity pulverized and distributed.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will beparticularly pointed out in the claim.

Referring to the drawings, Figure 1 is a perspective of a fertilizer-distributer constructed in accordance with my invention. Fig. 2 is a longitudinal vertical section. Fig. 3 is a transverse section. Fig. 4 is a perspective of the grinding-cone. Fig. 5 is a similar view in detail of the grinding hopper or cylinder.

Like numerals of reference indicate like 0 parts in all the figures of the drawings.

1 designates the oblong frame of the fertilizer-distributer, and at the front end of the same there is located a depending plow-standard 2, said standard being located at the center of the frame. The rear end of the frame is provided with depending inclined plow-standards 3, the locations of which are at opposite sides of the first mentioned standard. The firstmentioned standard 2 is designed to open the furrow, while the two latter standards are for the purpose of filling said furrow, and between said standards are located the fertilizerdistributing mechanism and the necessary 7 designates a cylinder located in rear of the wheel 5 and between the opposite sides of the frame-work. The cylinder is preferably cast in a single piece, and is provided at its upper side with an opening 8, over which is mounted an ordinary hopper 9. The interior of the cylinder is conical, and the internal surface thereof is toothed or serrated. 1O designates a shaft, which passes through one end of the cylinder and is journaled inabear- 6o ing in one of the side bars. The shaft is provided outside of the frame-work with a sprocket wheel or pulley 11, made removable, and connected to the shaft by means of abolt 12. This pulley is connected to and driven by the sprocket 6 by means of an endless chain 13. The pulley 11 being removable, other pulleys of differing sizes may be substituted, whereby the shaft 10 may be driven at various rates of speed for a purpose hereinafter 7o apparent. The opposite end of the shaft 10 takes bearing upon an adjustable bearingbolt 14, which is inserted through that side bar of the frame-work 1 opposite to the one in which the shaft 10 is journaled. Upon the shaft 10 is mounted rigidly a cone-shaped grinding-burr 15, which operates in connection with the roughened surface of the cylinder 7 and grinds thoroughly all fertilizers subjected thereto. By regulating the bear- 8o ing-bolt 14: the cone may be adjusted toward or away from the conical internal surface of the cylinder or hopper, and thus the degree and amount of pulverization may be regulated in accordance with the require- 8 5 ments. The lower side of the cylinder 7 is provided with a delivery-spout16,in which is mounted an adjustable cut-off 17. The rear end of the frame-work is provided with the usual rearwardly-inclined handles 18, and the front end with the proper draft appliances.

In operation the fertilizer is poured into the hopper and the machine is set in motion. The front plow opens the'furrow, and the fertilizer in a thoroughly pulverized state is fed in predetermined quantities into the bottom of the f u rrow, after which the rear shovels act to cover or close the furrow.

Having thus described my invention, what I claim is In a fertilizer-distributer, the combination, with the grinding-cylinder 7, provided at one side with the grinding-chamber flared toward one of its ends, the frame 1 for supporting the cylinder, and the hopper located above and communicating with an opening 8 formed ing', a gear-Wheel mounted upon the extended shaft, and means for imparting mot-ionto the gear, substantially as-speoified.

In testimony that I claim the foregoing as I 5 my own Ihave hereto affixed my signature in presenceof two witnesses.

WILSON A. DAVIS.
